Foglight for Application Operations 5.9.8.5 - Dependency Mapping User Guide

Creating and Maintaining Services

A service is a grouping of one or more components that interest you. This section presents workflows for grouping monitored resources into services, for investigating whether any service disruptions have occurred, and for editing existing services, as necessary.

After installing Foglight for Application Operations, additional dependency information about services is provided on the Service Operations Console. For more information, see View service-based dependencies.

To access the Create and Maintain Services dashboard, in the Foglight navigation panel, under Dashboards, click Dependency Mapping > Create and Maintain Services. You must log in to Foglight as a user with the Advanced Operator role.

From here, you can:

Build services from host dependencies: Use this workflow to build a new service, starting with a host having dependencies that you want to monitor.
Update service from dependency data: Use this workflow if you have existing Foglight for Dependency Mapping services and you would like to update them based on new or changing dependency information. The Dependency Mapping functionality reveals the dependencies that exist between objects within your existing services. It also identifies any objects that are external to these services, and have dependencies with other internal objects. You can update these services to include the newly discovered external objects that have dependencies. You can also use this dashboard to periodically monitor changes in your service dependencies and update them, as necessary.
Build services from service suggestions: Use this workflow to build services starting with a list of suggested groups of objects with discovered dependencies identified by the Dependency Mapping agents.

Build services from host dependencies

To navigate to the Build Services from Host Dependencies dashboard, on the Create and Maintain Services dashboard, click Build Services from Host Dependencies.

Name

Host name

IP

Host IP address

Application Components

To see a dependency graph that includes multiple hosts, click Preview . To see the dependency graph for one selected host, click the host name.
4
Click Next.
6
From the Add objects to list select one of the following options:
The Create a New Child Service dialog box appears.
b
Type the Name of the new child service and a short Description (this text appears in a dwell when you hover over a service name).
c
From the Tier list, select a tier from the available options; select auto if you want the system to automatically add this child service to an existing tier when its created.
d
Click Create Child Service.
To move a host into a different service, select it in the Group Selector and click Move. Alternatively, click the host on the view and, in the list that opens, click Move to another service.
In the Move to Another Service dialog box that appears, select the service where this host should be moved and click Move. The Selector Group tree and the display area are updated accordingly.
To exclude a host from a service, select it in the Group Selector and click Exclude. Alternatively, click the host on the view and, in the list that opens, click Exclude this item.
The <component_name> Details dialog box appears, displaying the host’s dependency information in table and graph formats (Dependency Details and Close-up Graph tabs, respectively).

Click Finish.

Update service from dependency data

The system scans your services for changes in the dependency data on request. The scan looks for new dependencies to hosts that are not contained by a service. It also looks for items inside the service with dependencies to other items inside the service that no longer exist. To scan and update a service definition based on these detected dependency changes, use the Update Service from Dependency Data dashboard.

To navigate to the Update Service from Dependency Data dashboard, on the Create and Maintain Services dashboard, click Update Service from Dependency Data.

The information presented is precalculated, based on the changes that occurred before the Last Change Detected. Selecting a service from the list displays the service dependency map in real time. Observed dependency changes are highlighted using a set of conventions, as presented in the legend (click Show Legend in the lower right corner of the dashboard).

Added Dependencies

Shows dependencies added as part of the latest change.

Removed Dependencies

Shows dependencies observed during the original time period that are no longer active.

Added Node

Shows items that are new to the dependency chain of the service, and are not part of the service yet. These are items that can be added to the service.

Removed Nodes

Shows items in the service that were previously involved in the dependency chain, but which are not involved anymore. These items are candidates for removal from the service, because they no longer have internal dependencies with other objects in that service.

a
Click Add items to service.
Add the selected host to the current service — select the Current service option, then click Next.
a
Select the Child service of the current service option, then click Next.

In the list that opens, click Show service membership.
The Impacted Services dialog box displays a list of services that contain the selected host, and their health status.

Build services from service suggestions

To navigate to the Build Services from Service Suggestions dashboard, on the Create and Maintain Services dashboard, click Build Services from Service Suggestions.

Using the dependency mapping functionality, Foglight automatically discovers the relationship between objects in your environment and suggests sets of components with discovered dependency chains, which may indicate that a group of objects should be monitored as a Foglight service.

Use this dashboard to build a service starting from a set of components with discovered dependencies, or modify existing services by adding or grouping objects, as necessary.

The Customize Service Definition wizard appears. The system automatically organizes objects that have process or application components that match into suggested services.
3
From the Add objects to list select one of the following options:
The Create a New Child Service dialog box appears.
b
Type the Name of the new child service and a short Description (this text appears in a dwell when you hover over a service name).
c
From the Tier list, select a tier from the list of options; select auto if you want the system to automatically add this child service to an existing tier when it is created.
d
Click Create Child Service.
To move a component into a different service, select it in the Group Selector and click Move. Alternatively, click the component on the view and, in the pop-up that opens, click Move to another service.
In the Move to a new service dialog box that appears, select the service where this component should be moved and click Move. The Selector Group tree and the display area are updated accordingly.
To exclude a component from a service, select it in the Group Selector and click Exclude. Alternatively, click the component on the view and, in the pop-up that opens, click Exclude this item.
The <component_name> Details dialog box appears, displaying dependency details for the selected component in table and graphic formats (Dependency Details and Close-up Graph tabs, respectively).
